Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503926, here are decompositions:

43 + 31503883 = 31503926
73 + 31503853 = 31503926
79 + 31503847 = 31503926
127 + 31503799 = 31503926
193 + 31503733 = 31503926
199 + 31503727 = 31503926
283 + 31503643 = 31503926
367 + 31503559 = 31503926

Showing the first eight; more decompositions exist.
